S r industries offers hygienic and sanitary pumps series in stainless steel which are positive rotary pumps. The parts which come in contact with the liquid are made from aisi 316 quality stainless steel alloys to meet exacting requirements of hygienic standard. These rotary pumps are available with salient feature as the rotors start to rotate, an expanding cavity is formed by rotation of the lobes thus creating a vacuum at the inlet port, drawing liquid in pumping chamber. The product liquid is then carried between the lobes and positively displaced thereby sealing itself against the internal faces of the pump casing and the other lobe chamber is filed with the product liquid. The pumps operate by a discharge cycles and finally the product liquid is forced or pressed out of discharge port of the pump in continuous smooth flow and pressure generated by the meshing of the lobe rotors.
